Frequently Asked Questions

Can I combine multiple images into a single PDF?

Yes. You can select multiple images at once or click "+ Add More" to include additional photos. You can easily reorder pages before compiling.

What page sizes are supported?

You can choose standard international A4, North American US Letter, or "Fit to Image" which creates page boundaries that match your exact image dimensions.

Will my image quality be preserved?

Yes. Images are embedded using high-resolution JPEG encoding with minimal compression artifacts, ensuring crisp text, diagrams, and photos.

Are my uploaded files sent to any server?

No. Every byte is processed locally inside your web browser. Neither your original images nor the resulting PDF file are ever uploaded or transmitted.
